This invention relates to improvements in connectors for electric wiresand cables.

The usual method of repairing electrical cords, wires and cables is toremove part of the insulation, individually twist the wire ends togetherand wrap them with tape. This type of repair is cumbersome,unsatisfactory and tedious. The preferred method of connecting wires isby soldering, but very few people have the equipment or knowledge toproperly solder wires. This method is also unsightly. With the presentinvention the novice can twist together the individual ends of the wiresof the cables much in usual manner, and then quickly encase them in theparts of the connector for the puipose of safely and surely connectingthe wires in a properly insulated relation. I am, of course, aware thatconnectors have heretofore been used, but in the main they do not makeproper provision for expeditious connection of the cables, since theyemploy conductor strips, screws, etc. in order to accomplish the actualsplice connection. With the present invention it is to be noted that noscrews or electrical conducting strips are associated directly with thewire portions of the cable to be connected.

Gther objects and advantages of this invention. will be apparent duringthe course of the following detailed description.

In the accompanying drawing, forming a part of this specification, andwherein similar reier ence characters designate corresponding partsthruout the several. views,

Figure 1 is a side elevation of the improved connector showing the endsof the cables extending therefrom.

Figure 2 is a plan view showing one section of the connector detachedfrom the other section, with the individual twisted ends of the wireschanneled in the section.

Figure 3 is a similar View of the complementary section (both sectionsare similarly formed).

Figure 4 is a longitudinal cross sectional view taken axially thru theconnector with the cables removed.

Figure 5 is a transverse cross sectional view taken substantially on theline 5--5 of Figure 1.

In the drawing, wherein for the purpose of illustration is shown only apreferred embodiment of the invention, the letter A may generallydesighate the improved connector. It consists oi of parts B and (3,connected by means I).

The parts B and C are of similar construction. The two of them arearranged in complementary relation to provide a complete connector. Eachpart consists of an elongated semioval-shaped insulation body, which maybe of rubber, thermosetting plastic, or other approved insulationmaterial. They may be molded, cast, stamped or other-- wise manufacturedin a single processing operation. The body includes an exterior convexsurface Ill having channels I l and l2 paralleling the side wallsthereof, formed by an intermediate channel separation portion M, thesurface of which is flush with the surfaces of the side walls 55 and I6defining the said channels H and it, as is apparent from the drawings.The ends of the portion l4 terminate short of the ends of the walls l5and I6 to provide a conduit portion ill for the channels. Each of theparts B and C is provided with a transverse central opening adapted toreceive the connecting means D. In addition, each part B and C isprovided with a stud 22, preferably formed integral therewith, at oneend of the projecting portion I i, extending normal to the flat surfaceof said portion I i; the said stud or member M at its opposite end beingprovided with a socket 24. Along each of the channels or grooves H and12 the material of the body section is serrated, preferably in the formof teeth which extend into the channels. preferably slightly below thenormal surfacing of these channels, so as to provide some space forclamping of the twisted wires. This permits the sections B and C tocompletely close and avoids cutting of the wires when the complementaryparts of the connector are assembled in surface to surface contact, asshown in Figure 5 of the drawings.

Concerning themode of using the connector, the ends it and SI of theelectrical cordage of cable have the insulation thereof removed forapproximately to expose the ends of the individual wires. The latter arethen individually twisted together much as in the usual manner of makinga spliced connection, and the said twisted ends are then placed in thechannels or grooves i l and I 2 of one part of the connector. The otherpart of the connector is then placed over the same, with the studportion 22 of one part of the con nector assembled in the socket 24 ofthe other part or the connector. This prevents turning movement of theparts relative to each other. The means D for clamping the parts of theconhector together is then assembled in the openings 2t. This meansconsists of a screw threaded shank bolt portion and a nut Eli. The outerends of the passageways 20 are enlarged to accommodate the head and nutof the bolt.

Various changes in the shape, size and arrange 3 ment of parts may bemade to the form of invention herein shown and described, withoutdeparting from the spirit of the invention or the scope of the followinclaims.

I claim:
